Computer Science Relational Model (Logical and Physical Schema Development) The conceptual model developed in phase 2 will be transformed into a logical and physical schema using the relational data model. The outcome of this transformation will be a relational schema. The schema should have the following components: Set of required relations All the integrity constraints Submission and Evaluation: A report consisting of the problem statement, ER diagram, relational schema And implement the database using SQL should include: All the tables properly defined /created All constraints properly defined For each table, few instances of data should be entered.
